I like your Muzzy , being made of titanium is also what I was after for my gen 2 . As you mention , the Japanese pipes in ti certainly look interesting , and well made , but very hard for me to find any / many reviews about performance increase etc . Even the exquisite Yoshi Ti pipe selection that are offered from Japan are rare to offer power increase info . Personally ended up going for the readily available and certainly one of the lightest ti pipes for gen 2 , Brocks CT Meg , full noise loud , but 3.79 kg bolted up . Cheers
